HAYPRESS.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed March 28, 1914. Serial No. 827,827.

To all whom zt may concern:

Be it known that I, Tnoams E. TURNER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Hay-Presses, of which the following is a full, clear, and exact specification.

My invention relates to hay presses.

The objects of the invention are to provide improved means for actuating the feeder through connections with the presser head whereby its movement will be positive and efficient, and simple in its construction, im proved means for controlling an orbital movement of the rack that actuates the presser head, and improved means for guiding the presser head in its relation with the frame of the machine. These objects are attained by mechanism, one embodiment of which is illustrated in the accompanying drawings, in which c Figure 1 is a side elevation of part of a hay press having my invention embodied in its construction; Fig. 2 is a detail part of the self-feeding mechanism; Fig. 3 is a partial end view of the power transmitting mechanism for guiding the orbital path of movement of the presser head actuating rack; Fig. 4 is a longitudinal section of part of Fig. 1; Fig. 5 is across section of Fig. 1 along line AB; and Fig. 6 is a top plan view of part of the rack controlling mechanism.

Referring to the drawings, wherein the same reference characters designate like parts throughout the several views, the base of the main frame comprises parallel side bars 1 upon opposite sides of the machine, 2 the bale chamber, 3 the press chamber, and 4 a feed hopper communicating with the press chamber.

5 represents a reciprocating presser head mounted in the press chamber and comprises a rib member 6 at its front upper side and downwardly converging rib members 7 having their upper ends connected with the member 6 at their upper ends.

8 represents rollers journaled upon their lower converging ends and adapted to travel upon the base members 1 of the main frame.

9 represents a transverse pin received by openings in the rib member 7 near their middle part, and 10 a rocking coupling member secured to the rear end of a plunger bar 11 and pivoted upon the pin 9, the opposite end of the plunger bar forming a rack bar 12, having oppositely disposed cylindrical teeth 13 forming a part thereof, and engaging with pinions 14 rotatable upon opposite sides of the bar and secured to the nner ends of shafts 15 that are journaled 1n bearlng boxes 16 integral with gear frame members 17, having their lower ends secured to the base frame member 1, and 18 represents power transmitting gears secured to "the opposite ends of the shafts and engaging with pinions 19 secured to a driven shaft 20 journaled in bearing boxes 21 integral with the upper ends of the gear frame members 17.

22 represents supplemental base frame members having their rear ends secured to the front ends of the frame members 1, and 23 represents oppositely disposed vertically arranged forwardly inclined cam members secured to the supplemental frame members that engage with rollers 24 carried by the front end of the rack bar 12 in a manner to lift the front end of the bar as it is actuated by the pinions 14 in returning the presser head to the front end of the press chamber, as shown by full lines in Fig. 1.

25 represents fixed guides integral with the gear frame members 17 and adapted to engage with the rollers 24 as they pass the opposite sides of the pinions l4, and 26 and 27 represent upper and lower rollers, respectively, carried by the gear frame members 17 and operative as sustaining guides for the rack bar 12 as it reciprocates above and below the axis of the pinions 14 in its orbital path, and driven continuously thereby in the operation of the machine.

The self-feeder mechanism includes a transverse rock shaft 28 journaled in bearingboxes 29 carried by the upper ends of vertically disposed frame members 30 secured to opposite sides of the front end of the bale chamber, and having their upper ends curved forward and secured to frame members 31 secured to the opposite sides of the press chamber.

.32 represents a curved feeder actuating arm having its rear end secured to the rock shaft 28 and its front end pivoted at 33 to a feeder head 34 intermediate its ends, the upper end of the feeder head being connected with the upper end of the frame member 31: by means of longitudinally adjustable links 35 in a manner to maintain the feeder head in a vertical position as the charge is carried from the feed hopper to the feed chamber in a well known way, and 36 represents a transverse bar secured to the curved arm 32 and having openings at its opposite ends that slidably receive stems 37 carried by a connecting bar 38, and 39 rep resents compression springs encircling the stems and operative between the two bars to yieldingly resist a swinging movement of the upper end of the feeder head 34 when swung upward and absorb the vibration of the feeder head. The stems 37 are held Within the openings in the bar 36 by means of pins 40.

41 represents arms secured to opposite ends of the rock shaft 28, and bell crank levers pivotally connected with the base frame members 1 upon opposite sides of the machine and having one arm of each connected with the arms 41 by means of vertically disposed links 43.

44 represents a transversely disposed shaft in front of the press chamber, carried by depending hangers 45 secured to the frame members 1, and 46 arms pivotally mounted upon opposite ends of the shaft 44 and having their free ends connected With the re maining arms of the bell crank levers 452 by means of links 47. Integral with the arms 46 and disposed inside of the frame members 1 are arms 48 having secured thereto the lower ends of bars 49, the opposite ends of the bars having secured thereto clip members 50, spaced apart therefrom at their upper ends and receiving between them the front ends of links 51 that are pivotally connected therewith by means of pins 52, the opposite ends of the links 51 being pivotally connected with the lower ends of the rib members 7 of the presser head by means of pins 53.

54 represents longitudinally arranged bars having their rear ends secured to the upper ends of the rib members 7 of the presser head upon opposite sides thereof and extending forward'and downward, and journaled at their front ends are flanged rollers 55 carried by studs 56 secured to the bars,

the rollers traveling between longitudinally disposed guide rails 57 spaced apart in parallel relation and secured to opposite sides of the frame of the machine.

58 represents a cross tie member having secured to its opposite ends the lower ends of vertically disposed bars 59, having their upper ends secured to bars 54 which in turn have their rear ends secured to the lower ends of ribs 7 and their front ends to the bars 54, the two pairs of bars 54 and 54 forming a rigid support for the presser head as it traverses the bale chamber. The tie member 58 tends to hold the flanges of the rollers 55 in contact with the outside of the guide rails 57 and preventing a spreading apart of the bars 54 and 54 at their front ends.

In operation the pinions 14 are rotated continuously in a direction indicated by the arrow in Fig. 4, and the rack bar 12 is reciproeated thereby in an orbital path in a manner to cause the presser head 5 to traverse the press chamber in opposite directions, and the cam members 23 engaging with the rollers 24 lift the front end of the bar as its rear end is passed to the upper side of the pinions 14. When the presser head is being drawn toward the front of the press chamber the arms 46 are turned toward the front of the machine by means of their connections with the presser head, and the links 47, connecting the arms with the bell crank levers 42, actuate the latter in a direction to rock the shaft 28 forward and cause the feeder head to descend into the press chamber 3, as shown by full lines in Fig. 1.

Having illustrated and described a preferred form of my invention, 1 do not wish that it be confined to the specific details of the construction as shown, it being understood that many minor changes may be made in its form without departing from the spirit of the invention.
